Like most on this forum I have had a knife in my pocket for a few years. I keep it around to have options or the power and freedom to choose. If I don't have it on me I don't have as much freedom to choose when faced with some situations including cutting a cardboard box.
When it comes to only having a knife in a situation that calls for a weapon of defense I found if all you have is a hammer everything turns into nail.
I would also recommend mentally going through the situation you put yourself in during a knife fight. You are trying to stop someone or change their mind from taking a bad action by cutting\stabbing them or showing force and you dont have time to put on rubber gloves.
